Definitions

  • This invention relates to an adjustable support apparatus.
  • the invention relates to an adjustable support apparatus for supporting, for example, a stretcher, bed, incubator, or other means on which or in which a patient is accommodated.
  • the adjustable support apparatus includes, what is known in the art as a "scissor-type" arrangement connecting upper and lowering elements or frames of the apparatus.
  • Adjustable support apparatuses having such scissor-type arrangements are, by way of example, shown in UK patent Nos. 2301282, 2172875 and 1198892.
  • Each of the apparatuses disclosed in these documents has at each side thereof a pair of cross members (first and second for ease of reference) which are pivotally connected to each other between their ends.
  • An end of the first cross member is pivotally connected to the upper element or frame and its opposite end is slidably connected to the lower element or frame.
  • An end of the other cross member at a position substantially below the pivotal connection of the first cross member to the upper element or frame, is pivotally connected to the lower element or frame and its opposite end is slidably connected to the upper element or frame, at a position substantially above the slidable connection of the first cross member to the lower element or frame.
  • a problem with such known scissor-type arrangements is that the upper element or frame is liable to excessive twisting when supporting a patient. Such twisting can be particularly severe when the patient's body weight is not evenly distributed through each of the connections of the scissor-type arrangement to the upper element or frame, i.e. if a patient sits/lies near one side or corner of the upper element or frame. Such twisting is a result of relative movement of the first and/or second cross member at its slidable connection to the lower or upper element or frame, respectively. This is highly undesirable and could result in a number of health and safety issues, such as injury to the patient and/or to the apparatus, particularly if the spacing between the upper and lower elements or frames is adjusted whilst the upper platform is unevenly loaded.
  • an adjustable support apparatus comprising:
  • tilting of the uppermost (relative to a ground surface) support element is reduced. This is because even if the uppermost support element is unevenly loaded, the load is distributed between the cross members at each side of the apparatus, thus inhibiting twisting of the uppermost support element.
  • a further advantage of the adjustable support apparatus in accordance with the first aspect of the invention is that the cross members at each side of the apparatus work in unison.
  • the adjustable support apparatus in accordance with the first aspect of the invention also assists in the stability of the apparatus during use.
  • a device for inhibiting relative movement between first and second support elements of an adjustable support apparatus when said apparatus is anchored to an anchoring means of a fixed body comprising:
  • Such a device in accordance with the second aspect of the invention inhibiting relative movement between the first and second support elements, which is particularly beneficial when, for example, the adjustable support apparatus is anchored to a floor of a vehicle, particularly when supporting a patient.
  • an adjustable support apparatus including a device according to the second aspect of the invention.
  • an adjustable support apparatus according to the first aspect of the invention including a device according to the second aspect of the invention.
  • Figures 1 to 7 all show an adjustable support apparatus 1 in accordance with the invention.
  • Figures 1 and 2 show the adjustable support apparatus 1 supporting a stretcher 2.
  • Figures 3 and 4 show the adjustable support apparatus 1 supporting an incubator 3.
  • Figures 5 to 7 show the adjustable support apparatus 1 without the stretcher 2 or incubator 3;
  • figures 5 and 7 show the adjustable support apparatus 1 in a lowered condition and
  • figure 6 shows the adjustable support apparatus 1 in a raised condition.
  • the configuration of the stretcher 2 and the incubator 3 are well known and are connected to the apparatus 1 by means well known in the art, and thus will not be discussed further.
  • the adjustable support apparatus 1 includes a lower support element 10 and an upper support element 12.
  • the lower support element 10 includes a pair of substantially parallel elongate side frame members 10 a , 10 b positioned at each side of the apparatus 1 , which are connected together at one end of the apparatus 1 by an end frame member 10 c and at an opposite end of the apparatus by an end frame member 10 d .
  • the end frame members 10 c , 10 d extend perpendicularly between the elongate side frame members 10 a , 10 b .
  • Each end of each elongate side frame member 10 a , 10 b is provided with a castor wheel 11.
  • Each castor wheel 11 is of conventional form and can be individually braked by a respective foot pedal 11 a . It will be appreciated, however, that other types or combinations of wheels could be utilised.
  • the upper support element 12 includes a pair of substantially parallel elongate side frame members 12 a , 12 b which are connected together at one end of the apparatus by an end frame member 12 c and at an opposite end of the apparatus by an end frame member 12 d .
  • the end frame members 12 c , 12 d extend perpendicularly between the elongate side frame members 12 a , 12 b .
  • the elongate side frame members 12 a , 12 b are also connected by an intermediate frame member 12 e , which is positioned substantially midway between the side frame members 12 a , 12 b , and which also extends perpendicularly between the elongate side frame members 12 a , 12 b .
  • each end of each side frame member 12 a , 12 b is provided with a downwardly extending stopper 22, each with upwardly extending recess therein.
  • the stoppers 22 each engage over a respective projecting cylindrical part 23 provided on each end of each side frame member 10 a , 10 b , below its respective stopper 22.
  • the purpose of the stoppers 22 and parts 23 is two-fold. Firstly, they ensure that even when the upper support element 12 is completely lowered (as will be discussed later) the upper and lower support elements 10, 12 do not engage each other directly (i.e. they define a safe lowermost condition of the upper support element 12), and secondly they provide location of the upper support element 12 relative to the lower support element 10 when upper support element 12 is completely lowered.
  • the lower support element 10 and the upper support element 12 are connected to each other, at each side of the apparatus 1, by a pair of cross embers 14, 16.
  • the configuration of the cross members 14, 16 connecting the elongate side frame members 10 a and 12 a is a mirror image of the cross members 14, 16 connecting the elongate side frame members 10 b and 12 b . Therefore only the configuration of the cross members 14, 16 connecting the elongate side frame members 10 a and 12 a will be discussed hereinafter.
  • the cross members 14, 16 are pivotally connected to each other between their ends at 15 by a conventional fastening, such as a fastener passing through apertures in both cross members 14, 16 with an appropriate bearing or bushing , if desired.
  • a conventional fastening such as a fastener passing through apertures in both cross members 14, 16 with an appropriate bearing or bushing , if desired.
  • the cross member 14 is pivotally connected at 17, adjacent the end frame member 10 d , to the elongate side frame member 10 a of the lower support element 10 and connected (described in more detail below) at its opposite end, indicated at 18, adjacent the end frame member 12 c , to the elongate side frame member 12 a of the upper support element 12.
  • the cross member 16 is pivotally connected at 19, adjacent the end frame member 12 d , to the elongate side frame member 12 a of the upper support element 12 and connected (described in more detail below) at its opposite end, indicated at 20, adjacent the end frame member 10 c , to the elongate side frame member 10 a of the lower support element 10.
  • the apparatus also includes actuating means in the form of a piston/cylinder 21, which is connected at one (lower) end to the lower support element 10 via a bracket (not shown) which is connected to the end frame member 10 d , and at an opposite (upper) end to the intermediate frame member 12c of the upper support element 12.
  • the piston/cylinder 21 is actuatable by a foot pedal (not shown) so as to effect movement of the upper support element 12 away from and towards the lower support element 10 so as to adjust the height of the apparatus 1 and thus any article supported thereon, such as, for examples, a stretcher, bed or incubator.
  • connection, indicated at 18, of the cross member 14 to the upper support element 12 is provided by a part 30 (see figures 8 and 9).
  • the components and operation of the connection indicated at 18 is mirrored on the opposite side of the apparatus 1, and thus will only be discussed with reference to the connection of the cross member 14 to the elongate side frame member 12 b of the upper support element 12.
  • the channel part 30 includes a pair of substantially parallel side walls 31 (lower), 32 (upper), which are spaced vertically from each other and are connected by a base wall 33.
  • the channel part 30 is connected to an inwardly facing wall of the side frame member 12 b by conventional fasteners passing through apertures in the base wall 33.
  • the upper side wall 32 is provided with a rack gear 34 having teeth which face the lower side wall 31.
  • the rack gear 34 extends along a majority of the upper wall 32, but it is not always required do so.
  • the rack gear 34 is engaged by a respective pinion gear 35 (shown in the cutaway view in figure 9) supported on one end of an axle 36, which axle 36 is supported in an aperture/bushing in the end of the cross member 14, and is free to rotate about its axis.
  • the rack gear 34 should, beneficially, be of suitable length so that teeth of the pinion gear 35 mesh at all times.
  • the opposite end of the axle 36 supports a pinion gear 35 on the opposite side of the apparatus 1, and thus the pinion gears 35 supported by both cross members 14 are rotationally fast with each other.
  • Each pinion gear 35 is covered by a cover 37.
  • the cover 37 substantially surrounds the pinion gear 35, and includes an aperture 38, adjacent the upper side wall 32, to permit engagement of teeth of the pinion gear 35 with teeth of the rack gear 34.
  • Upper and lower surfaces of the cover 37 are shaped so as to slot between the side walls 31, 32.
  • each cross member 16 to the elongate side frame members 10 a or 10 b of the lower support element 10 are indicated at 20 in figures 1 to 7.
  • Each of the connections indicated at 20 are identical in their components and operation to the connections indicated at 18. They each include a channel part 30, a rack gear 34 connected to the upper wall 32 of the channel part, and a pinion gear 35 supported on an axle 36, which axle is supported at each end by an aperture/bushing in the end of the cross member 16, and is free to rotate about its axis.
  • the pinion gears 35 are thus rotationally fast with each other.
  • Each pinion gear 35 is covered by a respective cover 37.
  • the piston/cylinder 21 is actuated by the foot pedal (i.e. in this example by moving the pedal upwardly to effect lowering of the upper support element 12 and repeated depression of the pedal downwardly to effect raising of the upper support element 12).
  • the ends of the cross members 14, 16 which are pivotally connected (i.e. adjacent the end frame members 10 d and 12 d ) to the upper and lower support elements 10, 12 pivot relative to their respective connections.
  • the opposite ends of the cross members 14, 16 i.e. those connections indicated at 18 and 20
  • each pinion gear 35 Upon lowering of the upper support element 12, each pinion gear 35 travels in the opposite direction along its respective rack gear 34 towards the end frame members 10 c or 12 c . Again, because of each pair of pinion gears (upper and lower) are connected by a respective axle 36, and thus cannot rotate relative to each other, even lowering of the upper support element 12 is achieved.
  • the connections indicated at 18, 20 also inhibit tilting/twisting of the upper support element 12 relative to the lower support element 10 when the upper support element 12 is unevenly loaded. Even if a load on the apparatus 1 is unevenly distributed, e.g. towards one corner of the upper support element 12 adjacent the connection of the end frame member 12 c and the elongate side frame member 12 a (when a patient sits near one corner of the apparatus 1), each pair of pinion gears 35 (upper and lower) can only move at the same rate because of their respective axles 36. Thus a load concentrated at one corner of the apparatus 1 will be distributed between both sides of the apparatus 1 and thus between both pairs of cross members 14, 16 at both sides of the apparatus 1.
  • connections indicated at 18 and the connections indicated at 20 may include respective rack gears 34 and pinion gears 35.
  • the connections indicated at 18 may each be adapted to a free-sliding arrangement (as shown in the prior art discussed above), thus removing the rack gear 34 and pinion gear 35 therefrom.
  • the connection indicated at 18 may be maintained in its described form with rack gear 34 and pinion gear 35, whilst the connections indicated at 20 may each be adapted to a free-sliding arrangement.
  • neither of these variations will work as well as the embodiment herein described, but will, in any event, still inhibit tilting/twisting of the upper support element 12 relative to the lower support element 10 when the upper support element 12 is unevenly loaded.
  • FIGS 10 and 11 show an anchoring means 40 for anchoring the apparatus 1 to a fixed body, such as a floor of a vehicle.
  • a fixed body such as a floor of a vehicle.
  • Each anchoring means 40 includes a substantially planar base member or plate 41, which is fixable to a floor of a vehicle by fasteners 42.
  • a substantially planar base member or plate 41 Connected to and extending upwardly from the base member 41, substantially perpendicularly away therefrom, are two side members 43, 44, each of which is substantially planar and has a respective top surface 43 a , 43 b , which is substantially parallel with the base member 41.
  • the side members 43, 44 are spaced from each other at each side of the base member 41.
  • the connection of each side member 43, 44 to the base member 41 is adjustable so that the side members 43, 44 can be positioned closer to or farther away from each other.
  • a bridging member 45 Extending between and connecting the side members 43, 44 is a bridging member 45, which is also substantially planar in shape and of a length dependent upon the spacing of the side members 43, 44.
  • An end of the side member 43 remote from its connection to the base member 41 includes a recess 48, which is positioned on the vertical centreline of the side member 43. Positioned at either side of the recess 48 are slots 46, 47. Each slot 46 or 47 is substantially parallel with a plane of the base member 41 and extends from an outermost edge of the side member 43 towards recess 48. The depth of each recess 46 or 47 tapers in a direction towards the recess 48.
  • the configuration of the side member 44 is a mirror image of the side member 43 and thus also includes a recess 48 and a pair of slots 46, 47.
  • Each end of the apparatus 1 can be anchored to the anchoring means 40 by a locking device, indicated at 50 in figures 11 and 12.
  • the locking device 50 connected to the end frame member 10d will be described; the locking device 50 connected to the opposite end of the apparatus 1 on the end frame member 10c is a mirror image thereof, except for some slight variations which will be discussed below.

  • the spacing of the side members 43, 44 of the anchoring means 40 a is wider than that of the spacing of the side members 43, 44 of the anchoring means 40 b . This also ensures that the apparatus 1 can only be engaged with the anchoring means 40 a , 40 b in one direction.
  • the apparatus 1 is then moved until the end frame member 10 d nears the anchoring means 40 b (of course, at the same time the end frame member 10 c also nears the anchoring means 40 a ).
  • the apparatus 1 is then moved farther until the spring-loaded plungers 53, 55 of the locking devices at both ends of the apparatus move along the slots 46, 47. As the slots are tapered, the spring-loaded plungers 53, 55 are both moved progressively inwardly.
  • the wheels 63, 64 abut a portion of their respective side member 43, 44 and ride up on to the top surface 43a or 43b of the side member 43, 44.
  • This abutment effects pivoting of the hook formations 61, 62 and moves the hook formations 61, 62 between the elongate member 71 and the end frame member 12 c , thus inhibiting relative movement between the upper and lower support elements 10, 12.
  • This is particularly beneficial, when the apparatus 1 is anchored to a floor of the vehicle and is being transported with, or without, a patient thereon.
  • the device ensures that the upper and lower support elements 10, 12 do not move excessively relative to each other, for example when the vehicle is cornering, braking and/or accelerating, or as a result of uneven road surface.
  • each spring-loaded plunger 53, 55 engages in its respective recess 48, thus anchoring the apparatus to both anchoring means 40 a , 40 b .
  • FIG. 13 A side view of the engagement of the hook formation 63 with the elongate member 71 is shown in figure 13.
  • Un-anchoring of the apparatus 1 from the anchoring means 40a, 40b is achieved by depression of the foot operable lever 47 on each locking device.
  • a locking device is provided at each end of the apparatus 1
  • unanchoring of the apparatus 1 will require two operators, one at each end of the apparatus 1 to simultaneously depress both foot operable levers 47.
  • a linkage could be provided between both foot operable levers 47, so that depression of either with cause both levers 47 to depress.
  • the apparatus 1 could be un-anchored by one operator.
